DEVICE FOR SECURING DESKS AND SEATS TO THE FLOOR.

SPECIFICATION forming part of Letters Patent No. 484,657, dated October18, 1892.

Application filed May 5,1892. Serial No. 431,902. (No model.)

To all whom it may concern:

Be it known that I, GEORGE A. HAMMOND, of Bennett, in the county of Lakeand State of Michigan, have invented certain new and useful Improvementsin Devices for Securing Desks and Seats to the Floor; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use it, reference being had to the accompanyingdrawings, which form part of this specification.

My invention relates to an improvement in devices for securing desks andseats to the floor; and it consists in the novel features ofconstruction which will be fully described hereinafter, and moreparticularly referred to in the claims.

The object of my invention is to mount a desk or seat in such a mannerthat it may be turned upon a pivot out of its normal position into theaisle, thus giving readyaccess to the floor space beneath it forsweeping and scrubbing.

Referring to the accompanying drawings, Figure 1 is a perspective viewof a combined desk and seat provided with my improvement. Figs. 2 and 3are detached views of the parts which constitute the attachment.

A represents a desk of any desired construction, which is arranged withothers along an aisle in a school-room or meeting-hall.

B 0 represent the legs of the desk at its respective ends.

0 represents a strip of board or metal which is secured to the floor,and projecting from the center thereof is the pivotal bolt D. Fastenedto the bottoms of the legs B is the strip E, having the opening F,through which projects the bolt D. Thus it will be seen that the desk ispivotally secured to the floor at this end.

G represents a cleat which is fastened to the floor parallel with thestrip 0. The upper surface of this cleat is inclined, and formed in itscenter is the opening H, and at the upper end of the inclined surface isthe rib or projection I.

Secured to the bottom of the leg 0' is the cleat J, which is providedwith an opening in its center, as shown, and journaled in this openingis the rollerK. At the end of this last-named cleat is the recess L,which when the desk is in its normal position registers with the rib I,and thus the desk is held from turning. The roller K serves to supportthe outer end of the seat in its movement on the pivot D, and when thedesk is turned back to its normal position it will be seen that theroller will run up the inclined strip G until the opening H is reached,into which it will drop, while at the same time the rib and recess arein engagement. The top of the cleat G is made sloping, so that when thedesk is being moved back to its normal position the rise of the strip Jand roller K thereon will not be any more abrupt than absolutelynecessary. As shown, the rise is gradual and the movement isaccomplished with ease. Oleat J is constructed with an inclined undersurface, so as to constitute its top alevel support for the feet of thedesk. Thus it will be seen that by elevating slightly the swinging endof the desk the same may be readily turned around when it is desired toclean the floor,and when finished it is easily swung back in positionand there securely held.

Having thus described my invention, I claim 1. The combination,with adesk having projecting legs at each of its ends and a pivotal supportfor one of the said ends, of a strip secured to the legs at the oppositeend, a roller j ournaled in the said strip, and a cleat secured to thefloor Which is provided with a depression in which the said rollerrests, substantially as shown and described.

2. The combination of a desk, legs therefor, a strip secured to one ofthe legs, a strip secured to the floor to which the said leg-strip ispivoted, a strip secured to the legs of the opposite end of the desk, aroller journaled in an opening in the said strip, a strip secured to thefloor, which is provided with an opening into which the said rollerrests, inclined rib I, and a corresponding inclined depression L on theadjacentfaces of the last-named strips, substantially as shown anddescribed.

In testimony whereof I affix my signature in presence of two Witnesses.

GEORGE A. HAMMOND.
